NOTES
1See Terminology section.
2Temperature range: B Version: â40°C to +105°C; typical speciï¬cations are at 25°C.
3Linearity is tested using a reduced code range: AD5332 (Code 8 to 255); AD5333 (Code 28 to 1023); AD5342/AD5343 (Code 115 to 4095).
4DC speciï¬cations tested with outputs unloaded.
5This corresponds to x codes. x = Deadband voltage/LSB size.
6Guaranteed by design and characterization, not production tested.
7In order for the ampliï¬er output to reach its minimum voltage, Offset Error must be negative. In order for the ampliï¬er output to reach its maximum voltage, V REF = VDD and
âOffset plus Gainâ Error must be positive.
Speciï¬cations subject to change without notice.
